We look at the division of 77600133 by 400 
The aim is to understand the frequency of 400 in 77600133.

Going ahead to step 1:
400 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 400

On to step 2:
400 can be fit into 77 0 times, resulting in a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Include the next digit (6) from the dividend after 77, then repeat: 776 / 400

Moving on to step 3:
If we divide 776 by 400, we get 1 and a remainder of 376.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 400 from 776 to get 376.
Take the next digit (0) from the dividend and append it to 376, then repeat: 3760 / 400

On to step 4:
The number 400 fits into 3760 9 times, leaving a remainder of 160.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtracting 3600 from 3760 leaves us with 160.
Fetch the next digit (0) from the dividend, attach it to 160 and continue: 1600 / 400

Let's proceed to step 5:
If we divide 1600 by 400, we get 4 and a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 194.0
The remainder is 0 after subtracting 1600 from 1600.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 400

Let's proceed to step 6:
If we divide 1 by 400, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 1940.0
Subtract 0 from 1 to get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 400

Let's proceed to step 7:
The number 400 fits into 13 0 times, leaving a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 19400.0
Subtract 0 from 13 to get 13.
Fetch the next digit (3) from the dividend, attach it to 13 and continue: 133 / 400

Going ahead to step 8:
400 goes into 133 0 times with a remainder of 133.
The number 0 becomes the next digit in our result. 
Result so far: 194000.0
If we subtract 0 from 133, we get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Going ahead to step 9:
400 can be fit into 1330 3 times, resulting in a remainder of 130.
Write down 3 as next digit of the result. 
Result so far: 194000.3
Subtract 1200 from 1330 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 10:
400 can be fit into 1300 3 times, resulting in a remainder of 100.
Put 3 as the next digit of the answer. 
Result so far: 194000.33
If we take 1200 away from 1300, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Our division results in 194000.33 with a remaining 0.1.
